How it works

A launchpad with nothing held back.

The same bonding-curve mechanics you know, with the whole supply on the curve from the first block and the liquidity locked at the end.

01

Name your coin

A name, a ticker, a picture. 1.00B tokens are minted in one transaction and go straight into the bonding curve — there is no team allocation, no presale and no vesting schedule, because there is nothing left over to allocate.

02

Take the first slice yourself

Your own first buy runs inside the launch transaction. The token does not exist until that transaction executes, so there is no block in which someone else can buy ahead of you.

03

Trade against the curve

800.00M tokens are sold along a constant-product curve priced in ETH. Every buy walks the price up, every sell walks it back down, and the price is always whatever the curve says — there is no order book and no liquidity to pull.

04

1% per trade, 20% of it to the creator

Each buy and sell pays 1%. 20% of that fee accrues to whoever launched the coin and can be withdrawn at any time; the rest funds the platform. For the first 10 minutes an extra fee of up to 4% is charged and decays to zero, which makes sniping the opening block expensive.

05

Graduate at 4.2 ETH

When the curve has taken in 4.2 ETH it shuts off. The raise and every token that was never sold are paired into a Uniswap V4 pool. The position belongs to the launch contract and nothing in it can remove liquidity, so the pool stays funded and trading continues there.

Questions

What stops the creator from rugging?

There is nothing to rug. The full supply is minted into the curve, so the creator holds no tokens unless they buy them like everyone else, and the liquidity created at graduation is locked in the launch contract rather than handed to anyone.

Can I move my tokens before graduation?

Only to and from the curve. While a curve is live its token can only be bought and sold through the launchpad, which is what stops anyone from seeding a DEX pair at a manipulated price ahead of graduation. After graduation it is an ordinary ERC20.

What does a launch cost?

Only gas, plus whatever you choose to spend on your own first buy.

What happens if the DEX call fails at graduation?

The buy that filled the curve still succeeds, and the curve is marked complete with the ETH still held by the contract. Anyone can then finalise the graduation from the token page once the router is reachable.

Which chains does this run on?

Ethereum and Robinhood Chain, plus their testnets. Robinhood Chain is an Arbitrum Orbit L2 that uses ETH for gas, so the same contracts and the same interface work on both.

Are the contracts audited?

No. They are covered by a test suite and use standard OpenZeppelin building blocks, but they have not been audited. Read them before putting money on the line.
